A switch with `sleep_rgb_or_color_temp: rgb_color` expresses its sleep colour
as RGB. `_apply_intensity` only walked RGB towards `sleep_rgb_color` on the
`adapt_until_sleep` path; everywhere else it re-derived RGB from the
interpolated colour temperature. Intensity 0 therefore produced
`color_temperature_to_rgb(sleep_color_temp)` rather than the configured
`sleep_rgb_color`, breaking the guarantee that 0 reproduces sleep mode.
The condition is now the switch's own configuration -- the sleep floor being in
force, and the sleep colour being expressed as RGB -- which subsumes the
`adapt_until_sleep` case and makes the `keep_rgb` parameter redundant.
The `minimum` floor still derives RGB from the colour temperature, because its
anchor is `min_color_temp`, a Kelvin, and the sleep colour is not the floor
there.
The existing test asserted the RGB match only when `force_rgb_color` was set,
so it stepped over this. Replaced with a test that asserts what was actually
promised, under both values of `adapt_until_sleep`, plus one pinning the
`minimum` floor's Kelvin-derived behaviour.

Adds one `number.adaptive_lighting_intensity_<name>` entity per
configuration, alongside the Sleep Mode / Adapt Brightness / Adapt Color
switches on the same device. It is a 0-100% slider that interpolates the
adaptive result towards the switch's floor:
output = floor_value + (adaptive_value - floor_value) * intensity / 100
100 short-circuits and returns the adaptive value untouched, so it is the
default and existing configurations behave exactly as before. 0 returns
the floor. In between the light stays fully adaptive -- the sun still
moves it at every setting, so it is a scaled curve rather than a frozen
level, which is what distinguishes this from simply scaling the
brightness band.
The floor is set by a new per-switch `intensity_floor` option: the
switch's sleep settings (`sleep_brightness`/`sleep_color_temp`) by
default, or its `min_brightness`/`min_color_temp`.
`transition_until_sleep` forces the sleep floor whatever `intensity_floor`
says. With that option on, the adaptive color temperature after sunset
descends below `min_color_temp` towards `sleep_color_temp`, so a
`min_color_temp` floor would sit above the adaptive value and turning the
dial down would make the light cooler.
Documented in the README's features and a new Intensity section, and on
the docs site as advanced/intensity.md.
